Welcome to 10 minute Bible Talks, where we connect the Bible to your life in the time it takes to get to work.

I'm Keith Simon. Right now we're going through the first book of the Bible,

Genesis. Do you know the promises that God has made to you and you believe that God

keeps his promises at the heart of every act of obedience to God is

faith in God's promises. And at the heart of every act of disobedience or sin against God is the failure to believe that God keeps his promises.

Sin is the very false belief that its promises are more sure, more satisfying than the promises of God.

We'll get back to that in just a moment, but first let's dive into Genesis 21.

When Abraham was 75 years old, God promised him and his wife Sarah that they would have a son.

Now obviously they were way past childbearing age, but what made that promise even more unlikely is that this was to be their first child.

You see, they've been unable to have children.

So God promised a child to an infertile couple in their 70s.

Well, good luck with that. A lot of years have passed since God made that promised Abraham.

God had made the promise.

Would God keep it?

I'm sure there were days when it was easier for Abraham to believe that God would be faithful to his promises. But my guess there

were a lot of days, a lot, a lot of days, when it was really hard for Abraham to believe

that God would give him a son. When Abraham was 99 years old, God

again appeared to him and told him and Sarah that they'd have a child within the

year. When Abraham and Sarah heard that, they laughed. The

laugh said, yeah right, sure we are. Genesis 21. Now the Lord was gracious to Sarah as he had said and the Lord did for Sarah what he had promised
